Subject: [PATCH 14/29] usb: remove old usb-host code

RH-Author: Gerd Hoffmann <kraxel@redhat.com>

Message-id: <1383648860-6526-2-git-send-email-kraxel@redhat.com>

Patchwork-id: 55374

O-Subject: [RHEL-7 qemu-kvm PATCH 1/1] usb: remove old usb-host code

Bugzilla: 1001144

RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>

RH-Acked-by: Bandan Das <bsd@redhat.com>

RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>

The usb-host code has been rewritten for qemu 1.5 to use libusb,

the old code has been left in as temporary fallback.  Now we are

two releases further out, targeting the 1.7 release.  No major

issues with the new code poped up until now.  Time to remove it

from tre tree.  Should we ever need it again for some reason --

git has a copy for us in the history.
